>Description:
gcj compiles non-abstract java classes which contain
abstract methods without complaining.

-------------------------
$ cat >Test.java
abstract class Abstract {
  public abstract int abstractMethod();
}

class Concrete extends Abstract { }
^D
$ gcj -C Test.java
$ javac Test.java
Test.java:9: class Test must be declared abstract. It does not define int getSize() from class Component.
public class Test extends Component {
             ^
Test.java:19: class Test is an abstract class. It can't be instantiated.
                new Test();
                ^
2 errors
$ rm *.class
$ gcj -c Test.java
Test.java:2: warning: abstract method in non-abstract class
-------------------------

Note that 'gcj -c' warns about it.
